When it comes to IELTS writing task 1, 25% of your marks are for the range of words you use. That means IELTS graph vocabulary is a very important component to review as you prepare for the Writing Task 1. You can start by checking out this IELTS writing task 1 vocabulary guide. And below, I’ll provide an overview of words and useful phrases to incorporate into your writing so that you can get top marks on the lexical resource category and a high band score overall. Basically, the better your IELTS writing chart vocabulary, the higher score you’ll get. It’s not hard, but there is a clear formula to doing well.

How to Use IELTS Graph Vocabulary in Writing Task 1

Because IELTS writing task 1 involves describing a graph or chart of some type, it will help to have a handle on IELTS writing chart vocabulary — words and phrases that help you write about the information on the chart or graph.

How are graphs described in IELTS? Let’s walk through the best vocabulary for the task, step by step.

1. Start With Introduction Phrases

Often ESL students start their essay with ‘The graph shows…’. While this is fine, the verb ‘shows’ could be replaced by a more exciting and high-level vocabulary word. Here are four different prompts to start your essay:

  • The graph illustrates the trends in…
  • The graph reveals information about the changes in…
  • The graph provides the differences between…
  • The graph presents how X has changed over a period of…
  • DO NOT write the word below or above in your introduction. i.e. The graph above/below shows…

2. Add Suitable Adverbs

Adverbs help express a relation of place, time, circumstance, manner, cause, and degree, and can greatly add some color and interest to your writing as well as show off your range of vocabulary. Unlike adjectives (which describe nouns), adverbs describe verbs, or actions. Here’s a great list of adverbs to use:

AdverbMeaning
ApproximatelyAlmost, but not completely exact; roughly
DramaticallyBy a quick and large amount
ErraticallyIn a way that is uneven or irregular
GraduallyBy slow degrees
MarkedlyNoticeably, significantly
SignificantlyIn a way that is worthy of attention; importantly
SlightlyTo a small degree
SlowlyAt a slow speed, not quickly
SteadilyIn a regular or even way

3. Use Appropriate Synonyms

Again using a variety of nouns and verbs for words like rise and fall will help increase your overall score. Here are some suggestions:

Rise (Noun)Rise (Verb)Fall (Verb)Fall (Noun)Fluctuate (Verb)
ClimbIncreaseCollapseDeclineBe erratic
IncreaseClimbDeclineDecreaseBe fitful
ImproveLeapDecreaseDeteriorationVary
JumpPick upDeteriorate DipRise and fall

Move upwardGrowthDrivePlunge
RocketDropFreefall
SkyrocketGo downSlide
SoarPlummetSlip
Shoot upPlungeDive
Pick upSlideReduction
SurgeSlip (back)Slump
RecoverSlump
Take a nosedive

4. Add Time Phrases

Below are some excellent time phrases with sentence examples:

Time Phrase Example Sentence

From...toFrom 1992 to 1996 there was a dramatic increase.

over the next/past/previous...Over the previous year, work-from-home rates sharply increased.
days/weeks/months/years/decadesFor several weeks, stock prices have remained stable.

Using IELTS Graph Vocabulary in a Model Essay

Look at the sample IELTS writing Task 1 graphs on the British Council website. Below is my model answer with useful words in bold:

The bar charts illustrate the trends in computer ownership, with a further classification by level of education, from 2002 to 2010.

Over the period, it can be observed that there was a significant surge in the percentage of the population that owned a computer. In the year 2002, only about 58% of the population owned a computer, whereas by 2010, this gradually increased to where over three-quarters of individuals had a home computer.

Looking at the information by level of education reveals that higher levels of education correspond to higher levels of computer ownership in both of those years. In 2002, a significantly low percentage of the population who did not finish high school had a computer, but this figure skyrocketed by 2010, going from 15% to over 40%. There were also dramatic climbs, of approximately 30 percentage points, for those with a high school diploma or an unfinished college education (reaching 65% and 85%, respectively, in 2010).

To conclude, during the last decade, there has been a substantial growth in computer ownership across all educational levels.

Other IELTS Graph Vocabulary Resources

Keep in mind that IELTS writing task 1 may contain one of several different types of infographic: a bar chart, pie chart, line graph, diagram, etc. Regardless of the type, you’ll want to have a good handle on IELTS writing chart vocabulary.

    Thank you Magoosh for the comprehensive guide. I’m a subscriber to you GMAT course and is now checking out IELTS.

    Wanna ask, I read and watched many other sources that says we should not write a conclusion. However, yours did.

    So, is it permissible or not permissible?

      Hi Joyce,

      The concluding sentence is optional–if you have time to write a concluding sentence after writing and reviewing your essay, then it looks good to have a concluding sentence. If you don’t have time to write a concluding essay or you’d rather focus on other parts of your essay, then it’s totally fine to leave it out. You can read more about this in our Complete Guide to IELTS Academic Writing Task 1.

    “Growth” is not an noun? Because in the board it’s saying that it is a verb

      Hi Julia,

      Thanks for pointing this out! It seems like a mistake on our part. We should probably change that to “grow”. I’ll make a note for our writing team to make this change 🙂

    I have two significant questions. The first one is related to the unit of measurement in over view. Is it academic? And the second one is of conclusion. Do we need to write conclusion?

      Hi Aakash, I’m afraid I don’t understand your first question. Can you please provide some more information?
      For your second question: a conclusion is not necessary. You can add one if you’d like, but it’s more important to spend time analyzing the graph.
